The polyp grabs at everything to fit to coders needs and distribution
needs, but it high and mighty ignores the users needs. Thank you very
much desktop environments for switching to PolypAudio.

On my Maverick install I don't have audio for 'desktop' apps (tested
with Youtube by Firefox only), there's only audio for JACK clients.

Usually this will solve the issue:

edubuntu at edubuntu:~$ cat /usr/share/alsa/cards/ICE1712.conf
# Configuration for the ICE1712 (Envy24) chip

ICE1712.pcm.front.0 {
	@args [ CARD ]
	@args.CARD {
		type string
	type route
	ttable.0.0 1
	ttable.1.1 1
	slave.pcm {
		type hw
		card $CARD
        #### fix PA issue ####
        slave.format S32_LE
        slave.channels 10

For this install it doesn't.

Paternalism doesn't stop, X became a PITA for tube monitors, the
kernel's default for CPU frequency scaling is 'corrected', so we'll save
around 1 W, for the coast of xruns all the time.

edubuntu at edubuntu:~$ cat /boot/config- | grep
edubuntu at edubuntu:~$ sudo cpufreq-selector -g performance
[sudo] password for edubuntu: 
edubuntu at edubuntu:~$ hwinfo --cpu | grep Clock
  Clock: 2100 MHz

What script does set frequency scaling to ondemand? This wasn't my

I installed wanderlust as mail client and emacs replaced my nautilus
default editor gedit, without my permission to do this.

Mouse wheel seldom works on my Maverick install.

Often grub.cfg is overwritten by a package without permission to do

The distro is working against my needs. I set up my Linux, but Ubuntu
re-edits some of those settings, by completely useless settings.

I'm near to switch to another distro.

Regarding to PulseAudio this won't be a help, but at least the rest
would be ok.

Before I do upgrades, I backup my Maverick install.

Regarding to the needs of the user, the distro shouldn't try to be
smarter as the user is. Ubuntu is MY TOOL, I do know what I do need and
what I don't need.

Pardon for running of the track.

What exactly are the advantages of PA in Ubuntu Studio, resp. for a DAW?

PA needs to be turned of by default.
